"Create new theme" button doesn't creates a valid new theme

If the user doesn't customize anything, clicking on "Create new theme" button redirects to

http://localhost:8080/xwiki/bin/inline/Theme+name../Main?template=ColorThemes.ColorThemeTemplate&title=Theme%20name...

creating a

http://localhost:8080/xwiki/bin/view/Theme+name../Main

if you look in the Space AllDocs, see index.png, but this page links to

http://localhost:8080/xwiki/bin/view/Theme+name../

which doesn't exists.

The correct behavior is to create a new page inside the "ColorThemes" space named "Theme name".
I guess the problem are the dots "..."
